HDC1000 Battery Status Datasheet Error

Other Parts Discussed in Thread: HDC1000

Section 8.3.2 of the HDC1000 datasheet says that the battery status is reported in the TRES field (Bit 11). I think that it should say BTST field as shown in 8.6.3.


Also, I don't get BTST to change signs until the battery voltage is 2.5V (not 2.8V). And, it will only read that signal that way once. It requires a reset to read it again. (I am checking the configuration register directly after a read of temperature and humidity).

  • Am I supposed to do a full write to the configuration register (pointer/dataMSB/dataMSB) before reading the BTST bit? My first interpretation of "This is reported in the TRES field (register address 0x00:bit[11]) which is updated after POR and after each measurement request" was that BTST was updated after every measurement of humidity or temperature. Does measurement request include humidity and temperature or is it limited to the configuration register and does it even include the configuration register?

    Thanks!
